Endometriosis of bilateral ureters, unspecified depth

This code signifies the presence of endometrial tissue affecting both the left and right ureters, the tubes that carry urine from the kidneys to the bladder. The specific extent or depth of the endometrial invasion into the ureteral wall is not documented.

Use this code when medical record documentation confirms endometriosis involving both ureters, but the physician does not specify whether the involvement is superficial, deep, or full-thickness. This code is appropriate when imaging (e.g., MRI, CT) or surgical findings indicate bilateral ureteral involvement without further detail on depth.

• Requires documentation of bilateral ureteral involvement.
• Only use when the depth of involvement is unspecified; if depth is known, a more specific code should be selected.
• Always sequence after the primary diagnosis for endometriosis (e.g., N80.A- for endometriosis of the ureter).
